Computational theories of vision
Neuroscientists study the brain at many different levels, from molecular to psychological. Despite progress on many of these levels, there is a disappointing lack of coherence in neuroscience research: we have yet to find an overarching theoretical framework for understanding what the brain does. Vision is one of the most intensively studied areas of brain function. Yet, even in this field, the...
متن کاملCan Computational Goals Inform Theories of Vision?
One of the most lasting contributions of Marr's posthumous book is his articulation of the different "levels of analysis" that are needed to understand vision. Although a variety of work has examined how these different levels are related, there is comparatively little examination of the assumptions on which his proposed levels rest, or the plausibility of the approach Marr articulated given th...
متن کاملCognitive Neuroscience: Trickle-Down Theories of Vision
The visual cortex is not a passive recipient of information: predictions about incoming stimuli are made based on experience, partial information and the consequences of inferences. A combination of imaging studies in the human brain has now led to the proposal that the orbitofrontal cortex is a key source of top-down predictions leading to object recognition.
متن کاملThe Viewer's Place in Theories of Vision
Analyses of vision have tended to focus on what may be under observation rather than considering the larger configuration including observer and observed. It i s , however, possible to think systematically about the "missing l ink" of observer/observed relationships. The paper aims to c lar i fy the logic associated with these relat ionships. At least three main types of observer/ observed rela...
متن کاملReflections on abnormal colour vision and theories of colour.
Historically, physiology is the daughter of pathology. Healthy people struggling with an overwhelming nature had no time to bother with the workings of their organs, and doctors-naturallywere always preoccupied with disease. For them the argument from malfunction to normal function has become almost second nature and the successes of this approach in such fields as neurology, endocrinology, and...
